Arsenal are sweating over the fitness of Olivier Giroud after the French striker limped off during the 4-0 win at Swansea City on Saturday.

The Gunners striker - who opened the scoring on 37 minutes at the Liberty - picked up a knock midway through the first half and it was clearly causing him discomfort as he struggled on until the break.

He surprisingly emerged for the start of the second half, but was withdrawn on the hour mark and replaced by Alex Oxlade-Chamberlain.
